XCOM 2 is the sequel in the highly successful XCOM series, offering a complex tactical strategy game in an alien invasion setting. Ever since its initial release in 2016, the game has been highly acclaimed by both gamers and critics alike. While XCOM 2 highly emphasizes challenging and engaging game play, there are also many positive benefits that the game provides.

Firstly, XCOM 2 provides strategic and tactical elements which are extremely interesting and satisfying to engage in. From choosing which missions or enemy types to tackle, to constructing and managing a base as well as researching new weapons and equipment, there are a myriad of opportunities to craft your own unique strategies to succeed in the game. This means that even after you beat the game the first time you'll most likely find yourself going back for another playthrough to test different strategies that you didn't explore before.

Furthermore, playing XCOM 2 has proven to boost player's psychological well-being. This can be attributed to a phenomenon known as "flow", which describes an optimal state of concentration and engagement where time and user's worries seem to disappear. As XCOM 2 demands considerable attention from its players to analyze and take into account all available options, it leads to immersion and focus on the gameplay. It’s both entertaining and allows for development, as it encourages the continual acquisition of skills and knowledge.

One of XCOM 2's most important benefits lies in its replayability. The game's high difficulty levels ensures that players are always kept on their toes, as even experienced players can find some stages to be extremely challenging. Multiple unique difficulty levels allow players to adjust difficulty levels according to their experience and capability, and even more so as they get better at the game.

Lastly, with its cooperative multiplayer mode, XCOM 2 offers the unique opportunity for friends or family members to play the game together. This allows players to collaborate in order to tackle difficult missions and share their strategies to succeed. In addition, by having friends to play with, players can socialize and interact with each other in ways that offline games never allowed before.

Overall, XCOM 2 provides an immensely enjoyable and rewarding experience to its players. With its combination of engaging and captivating game play as well as its numerous positive benefits, the game continues to be a favorite for many gamers.
